Efficacy will be assessed primarily by computed tomography (CT) analysis of percent bone bridging across the subtalar joint at both 12 and 24 weeks post-op. Outcome scores will also be administered to compare general health and foot function between the two groups at baseline and at multiple post-op follow-up visits. Additional resource utilization (i.e. additional clinic and/or hospital admissions) will also be compared between the two groups post-op.
